Hi jeffkhoury,

Well, If the programs you're trying to use are only 32 bit compatible then you can't use them in 64 bit. You'll have to find alternative programs that are 64 bit compatible. As to if you want a registry cleaner program you can use CCleaner. Many use it with good results. There is a list of 32 and 64 bit compatible programs in this list.

If you are having problems with errors you can run System File Checker and Checkdisk to see if it helps with any missing/corrupted files.
